3. EM12c EM12c was announced at Oracle Open World, Oct. 2011.
EM12c was Oracle’s answer to business’ reach into Cloud environments, which offers the ability to setup, deliver and manage them.
Administrators, through a single console, can now monitor usage, setup metering, chargeback for users, manage deployed applications, manage issues and link applications to MOS directly.

4. Why We Monitor our Databases
Pro-active notification of issues before resulting in outages/impact to users.
Awareness of performance, resource usage and demands.
Data collection to investigate performance issues- current, recent and historical.
Capacity planning.
Automation of maintenance work.

5. Monitoring and Notification Downfalls
Yahoo News- Over 70% of workers would give up showers to eliminate unnecessary s.
Paging with “Successful” and/or “I’m OK”.
Not alerting for enough types of failures, instead covering with when complete.
Paging on “Warning”
Setting Critical thresholds too high vs. giving time to correct.

6. Presentation Agenda EM Architecture
EM Incident Rules and the Incident Manager
Metric Extensions- The Why and the How.
Performance Pages
Top Activity
Diagnosing Issues
SQL Monitor
ASH Analytics

7. Simple EM Architecture
Oracle Repository stores data in an Oracle database.
OMS (Oracle Management Service)
Targets with OMA(Oracle Management Agent)/Plug-ins upload data to OMS.
Cloud Control Console, (aka EM Console) Used to view data through interaction with OMS.

8. Effective Monitoring with Incident Manager

9. Creating Incidents From Alerts

10. Incident Rules From EM12c Console Setup Incidents
Incident Rules/ Job Events

11. Incident Rule Sets
Two Non-Editable, Main Rule Sets Come with EM12c Installation,
Incident Management
Event Management

12. Incident Management Rules- Broken Down
Incident Creation for metric alerts
Auto- Clear rule for metric alert older then 7 days.
Auto-Clear rule for job status change for terminal status events.
SLA Incident Creation
Incident Creation for Target Unreachable, Down and Error.
Clear ADP, (Applicaton Dependency and Performance) alerts without incident after 7 days.
Incident creation rule for high-availability events.

13. Utilizing Existing Rule Sets
Disable existing, Non-editable, system generated, incident management rule set.
Quality Rule Set, but needs to be editable.
Need to Copy the incident rule set.
Enhance or add our own rules to the new rule set.

14. Disabling and Copying Rulesets

15. Copying a Rule Set Fill in new name of Incident Rule Set.
Defaults to all targets, exclude, change to target types or specific types.
Enable if copying a disabled rule set.

16. Copying Ruleset, Rules Tab
Click on the Rules Tab
You can Edit Existing rules, enhancing, updating or changing default settings.
Remove any unwanted rules.
Add specific rules for your environment.

17. Copying Ruleset, Co-authors

18. Rules vs. Metric Thresholds
Set globally.
Independent of database metric settings.

19. Metric Settings Set at database level unless using a template.
In BP1, only set with warning thresholds.
Good reason to use a template.

20. What Are Metric Extensions?
A dynamically configured extensions feature allowing to monitor environment specific conditions.
Simplifies monitoring of operational processes that once only existed outside of the EM12c console.
Eliminates requirements for secondary monitoring and management tools.
Eliminate need for external scripting that may require more monitoring logic than EM Jobs can provide.

21. Metric Extensions Details
Metric Extensions replace the formerly known “User Defined Metrics”
User Defined Metrics were limited to database and host types, no longer with Metric Extensions.
Ability to build a metric extensions library to utilize for your own environment.
Full development cycle support
Using specific protocols , the Oracle Integration Adapter gathers data about targets for use with metrics extensions.
A simple wizard allows for easy development and refinement of metric extensions.
Ability to test metrics using the “Test Page” allows an ability to run real-time metric evaluations to ensure definitions and scripts are free of errors before deploying.

22. Development Life Cycle

23. Enterprise > Monitoring > Metric Extensions

24. Metric Extensions Summary
Create development metric extension, wizard will simplify process.
Test with test page and verify that all steps, all features of the metric extension test correctly.
Deploy to target separately or to groups.
Utilize to fulfill any missing areas in monitoring environment.

Top sessions, clients, etc. on left in drop down.

30. Here’s our spike, which waits?
Commonly, focus on pink, orange, red and brown for issues.
Network and queuing do have opportunities for tuning, as well.
Green and blue are expected, but also part of problems when over utilized.

31. We’re in the Red, (Orange, too!)
Inspect High % use.
Red, orange, brown and pink.

34. What ASH Tells Us

35. The Icing on the Cake
Duh, add some memory to the EM12c box! 

36. SQL Monitor Elapsed Time SQL_ID, Beginning SQL Text.
Parallel, Waits and Execution Time

37. Top Activity, ASH style Ability to choose timelines by: Hour Day
Week Month
Calendar Custom

38. Familiar Interface
Changes to interface were minimal for user comfort

39. Sql Details View

40. Load Map
New Visual Way of Showing Data, Multiple Ways!

41. ASH Analytics Summary Future of “Top Activity”
Easy Agent Deployment through EM12c Console
Comfortable Interface for those familiar with Previous Versions.
Cool new features, new learning curve for some.
Oracle user DOES NOT need sudo, disregard the instructions.
